  • Roundup: Bubbling Ice, Black Carbon, and Glacial Advance

    The sound of glaciers A new article in the scientific journal Geophysical Research Letters, titled Unusually loud ambient noise in tidewater glacier fjords: A signal of ice melt, tracks glacial melt by recording the sounds of the glaciers bubbling underwater in glacial bays. Check out videos of the unique sounds below, and read the article here.  …

  • Photo Friday: Cryoconites and Glacier Tables

    Have you ever seen dark cavities on glaciers, which are also referred to as “cryoconites”? These holes, which can be meters deep,are created from debris on top of glaciers. Dark-colored debris, including soot, dust, and pollen, speed up the melting process of glacial ice as a consequence of their low reflectivity to incoming sunlight. In…

  • Roundup: Black Carbon, Winds, and Supraglacial Lakes

    Light-absorbing Particles in Peru “Glaciers in the tropical Andes have been rapidly losing mass since the 1970s. In addition to the documented increase in temperature, increases in light-absorbing particles deposited on glaciers could be contributing to the observed glacier loss. Here we report on measurements of lightabsorbing particles sampled from glaciers during three surveys in…

  • Roundup: Rock Avalanche, Melting Sound, Black Carbon

    Landslides on Glaciers “The chapter looks mainly at massive rock slope failures that generate high-speed, long- runout rock avalanches onto glaciers in high mountains, from subpolar through tropical latitudes. Drastic modifications of mountain landscapes and destructive impacts occur, and initiate other, longer-term hazards. Worst-case calamities are where mass flows continue into inhabited areas below the…

  • Roundup: New Stories on Black Carbon

    We feature three stories, all of which focus on black carbon. This atmospheric pollutant plays an important role in accelerating glacier retreat. Moreover, policies can be designed to reduce it, by supporting alternative fuels and improved technologies. Reductions in black carbon also bring health benefits, since this substance leads to pulmonary diseases. Story 1: Ice…

  • Major Conference Attracts Continuing Attention to Black Carbon

    This past month, the International Centre for Integrated Mountain Development (ICIMOD) and the Nepalese Ministry of Science, Technology, and Environment hosted the International Conference on Mountain People Adapting to Climate Change. The large attendance and extensive coverage of this conference brought a great deal of attention for the Hindu Kush Himalaya region and its specific…
